 For $n=1$, a field on a 0-manifold $P$ is a labeling of each point of $P$ with
 an object (0-morphism) of the 1-category $C$.

+It is customary when drawing string diagrams to omit identity morphisms.
+In the above context, this corresponds to erasing cells which are labeled by identity morphisms.
+The resulting structure might not, strictly speaking, be a cell complex.
+So when we write ``cell complex" above we really mean a stratification which can be
+refined to a genuine cell complex.
